Any tips for Cleaning and polishing a chevy intake manifold?

I have a weiand cast aluminum intake manifold for my small block chevrolet engine. It was one that was not coated from the factory so it has gotten a little dirty over the last year since i put it on. I read up on a few things and asked around, and apparently aluminum is porus so it will hold in dirt and old and other junk. Does anybody know any affective (and preferably inexpensive) cleaners for something like this? Also, does anybody know anything that i could use to coat this like they would in the factory so it has the chrome look to it?

I don't know about "inexpensive", but Eastwood makes a great aluminum manifold polishing kit. It has the rouge and tripoli buffing compounds, the grease, and an assortment of buffing cones and sanding bits to go from beginning to end with this job. The kit is somewhere around 80 bucks list.

If you have the buffing/sanding stuff, you can get away with just the additional aluminum specific compounds.

Or, you can try to clean the heck out of it - use degreasing compound and foaming engine cleaner to get most of the stuff off of it, then hit it with a heat resistant aluminum paint. In order to do this correctly, you need to get that intake seriously grease-free. I painted one intake successfully (although it was to match the "corporate blue" color). It held up nicely for 5 years going (until I got rid of the engine).
